Full coverage dental insurance provides comprehensive dental benefits for preventive, basic, and major dental procedures. Some of the most common procedures included are exams, x-rays, fluorides, sealants, fillings, extractions, denture adjustment and repair, crowns, root canals, in-lays, on-lays, dentures, oral surgery, fixed prosthetics, endodontics, periodontics, etc. Full coverage dental insurance provides the most dental coverage available compared to other plans. It is the best possible type of dental insurance plan to have simply because it covers major work which is the most expensive. If you have a plan that is not full coverage dental insurance and you need a crown, root canal, oral surgery, serious extraction, or etc. – you will end up paying significantly higher out of pocket dental care expenses.
